Aquarius and Scorpio are the smartest zodiac signs, astrologists say—but for two very different reasons. Those born under the Aquarius sign have the highest levels of analytical intelligence, which is measured by cognitive ability and IQ. Scorpios, on the other hand, have more perceptive smarts; they are best at realistically assessing and understanding the world at large. (Find out the healthiest zodiac sign of 2018.)

That’s not to say that other zodiac signs aren’t intelligent in their own ways. In fact, Geminis and Libras have plenty of mental smarts too, according to Neil Crabtree, an astrologist at the Mayo School of Astrology. Cancer and Pisces are the most emotionally intelligent; in other words, they are excel at recognizing and reasoning with their own and others’ feelings.

On the other hand, the earth signs—Taurus, Virgo, and Capricorn—demonstrate practical intelligence. And the fire signs (Aries, Leo, and Sagitarrius) tend to be the most intuitive, making them more inclined to take risks and fill leadership positions.
